Your core works where nobody can see it. Not you. Not your trainer. Not your physio. Until now.

A patent-pending wearable shows you your core working — in session, rep by rep.

The problem

Several levels too high.

Think about what you ask of your body. A run. A CrossFit session. A reformer Pilates class. A return to sport after injury. Each one assumes a level of function underneath it.

The True Core™ Assessment

Black and white.
No guessing.

It measures your level of function honestly, then teaches you exactly what you need to do to train at your level — and builds everything else around that.

  1. 01

    Black and white

    A clear, measured answer about your level of function. No spin, no flattery.

  2. 02

    Transparent

    You see exactly what I see, on the screen, as it is measured.

  3. 03

    Your level

    You train at your level of function — not the class’s, not the app’s, not the one you had five years ago.

  4. 04

    Built around you

    A full rehab, exercise and fitness programme, climbing to the level your goals require.

The method

Learn. Feel. Do.

  1. Two people in True Core shirts smiling together in the True Core studio, in front of the squat rack and a forest mural.01 / 03

    Learn

    The first stage of learning. The latest anatomy visuals, integrated with three proprietary concepts that let you see movement from a perspective no other approach gives you.

  2. A coach in a True Core shirt working one-to-one with a woman who is seated on the turf holding a medicine ball.02 / 03

    Feel

    You feel what you’ve learned, through high-grade one-to-one coaching with me — a sports physiotherapist and educator who has mastered the core in my own body and teaches it to professionals. And with the tech in session, you don’t only feel it working. You see it.

  3. A man in a True Core shirt balancing on a tractor tyre while working battle ropes, with a coach watching, in the outdoor training area.03 / 03

    Do

    You perform your newly acquired skills — in practice, in training and in sport — and elevate your functional capability where it actually counts.

Worth knowing

For the curious.

The way in

It starts with an assessment.

Your level of function measured. The gap to your goal made visible. Your programme built from there — your scores, your reports and your history in one place.
